Introduction

• Skinput turns our body into touch screen interface

• This technology uses the screen as the tracking surface or the unique input device

• It was developed by Chris Harrison, Densely Tan, and Dan Morris of the Microsoft Research's Computational User Experiences Group(MRCUEG)

PRINCIPLE OF SKINPUT

It listens to the vibrations in the body.

Skin put also responds to various hand gestures.

The arm itself is an instrument.

Equipment required

• It needs Bluetooth connection.

• It uses a microchip-sized Pico projector to display menu.

• An acoustic detector to detect sound vibrations.

Skin Interface

• The three input location sets evaluated in the study.

Waves Generated

• FIG: Transverse wave propagation: Finger impacts displace the skin, creating transverse waves (ripples). The sensor is activated as the wave passes underneath it.

FIG: Longitudinal wave propagation: Finger impacts create longitudinal (compressive) waves that cause internal skeletal structures to vibrate. This, in turn, creates longitudinal waves that emanate outwards from the bone (along its entire length) toward the skin.

BIO- ACOUSTICS: SENSING

These signals need to be sensed and worked upon.This is done by wearing the wave sensor arm band.

HOW IT WORKS

• In Skinput, a keyboard, menu, or other graphics are beamed onto a user's palm and forearm from a Pico projector embedded in an armband.

• An acoustic detector in the armband then determines which part of the display is activated by the user's touch.

• Their software matches sound frequencies to specific skin locations, allowing the system to determine which “skin button” the user pressed.

Processing : Model

Advantages No need to interact with the gadget directly.

No need to worry about keypad.

People with larger fingers get trouble in navigating tiny buttons and keyboards on mobile phones. With skinput that problem disappears.

Skinput will bring in a new way of operating a mobile phone, by turning a persons hand into a keyboard and forearm into a screen.

IMPLEMENTATIONIMPLEMENTATION ON PARALYZED PERSON OR PHYSICALLY DISABLE PERSON.

If a person is paralyzed or physically disable we can implement this technology. The feature of skinput technology provides a projected graphical interface on the skin, so the person who is paralyzed or physically disable they can use it easily like making a call, playing game, control music player application etc.

IMPLEMENTATION IN EDUCATION SYSTEM

Through the help of Skinput technology we can implement in education system like we can use calculator or browsing

through a mobile phone etc..

USING FINGERS AS CONTROL PAD OF GAME

• Through Skinput we can play games with just the movement of our hands. This will introduce a totally new era of gaming.

Making a Phone Call Using Skinput

• We can turn our arm into a cell phone It will be possible to make calls by just typing numbers that flash on your

• forearm[6]. All other functions can also be performed using Skinput. We can also increase or decrease the volume or

• change the track of our music players like the i-pod without actually touching the gadget.

Applications

I pods

Gaming

Mobile

Simple browser systems

• Small Sized Pico-projector • Wrist watch size sensor armband

Future Implementations

Conclusion

• Skin put allows the human body as an input surface.

• This system performs well even when the body is in motion

• Skin put technology provides an always available mobile input system that does not require a user to carry or pick up a device.
